1. Repeat the above test steps 1 to 2.
2. Set
at their rated value till 1 minute.
3. Ensure that the active and reactive energy values are less than the
setting default values respectively.
4. Check that EAFALM and ERFALM are low.
5. Increase the supply currents or voltage in next 1 minute cycle such that the active or
reactive energy values are greater than the
respectively.
6. Check that EAFALM and ERFALM are high after 1 minute.
7. Similarly the testing can be done for EARALM and ERRALM outputs by changing the power
inputs directions through direction settings.

Completing the test

Continue to test another function or end the test by changing the
Restore connections and settings to the original values, if changed for testing purposes.

Station communication

11.15.1 Multiple command and transmit MULTICMDRCV /
MULTICMDSND
The multiple command and transmit function (MULTICMDRCV / MULTICMDSND) is only
applicable for horizontal communication.
Test of the multiple command function block and multiple transmit is recommended to be
performed in a system, that is, either in a complete delivery system as an acceptance test
(FAT/SAT) or as parts of that system, because the command function blocks are connected in
a delivery-specific way between bays and the station level and transmit.
Command and transmit function blocks included in the operation of different built-in
functions must be tested at the same time as their corresponding functions.

Remote communication

11.16.1

Binary signal transfer

Prepare the IED for verification of settings as outlined in section
settings".
To perform a test of the binary signal transfer functions, the hardware (LDCM) and binary
input and output signals to transfer must be configured as required by the application.
There are two types of internal self-supervision of the binary signal transfer:
• The I/O-circuit board is supervised as an I/O module. For example it generates FAIL if the
board is not inserted. I/O-modules not configured are not supervised.
• The communication is supervised and the signal COMFAIL is generated if a
communication error is detected.
Status for inputs and outputs as well as self-supervision status are available from the local
HMI under
Line differential protection RED670
